Question
An agronomic wants to see if introducing sterile males of an insect problem to limit the pest population instead of applying insecticide will result in a higher corn production. The plots are separated into two categories. In the first group, insecticide is employed, whereas in the second group, sterilised male insects are used. The yields are listed in bushels in the table below.

Use a = 0.01 b) Find the 98% confidence interval of the difference in means.
